Important Notes

•This calculator provides estimates only and does not constitute legal or tax advice. Please consult a qualified real estate lawyer or tax professional before making financial decisions.
•Results are based on legislation as of June 2026. Tax rules may change. This tool applies to Ontario new home purchases only.
•These rebate programs have changed several times in the past year and may change again. We do our best to keep this calculator current, but the official CRA forms (GST190 and the RC7190-ON schedule) are the authoritative source and may calculate your specific situation differently — always confirm your final numbers with the CRA or your tax professional before relying on them.
•Enter your pre-tax agreement price (before HST) — the same base the CRA uses on its rebate forms. The “Builder Rebate (in price)” amount reflects the standard rebate builders typically credit at closing; anything above that is paid directly by you and must be claimed from the CRA.
•The Ontario provincial enhancement (up to $80,000) draws on the same Bill 114 (HST Relief Implementation Act) that received Royal Assent on May 12, 2026, and is now in force.
•The expanded HST rebate for all buyers (April 1, 2026 – March 31, 2027) is fully in force: Ontario's portion received Royal Assent on May 12, 2026 (Bill 114, HST Relief Implementation Act), and the federal cost-sharing regulations extending it to non-first-time buyers were finalized June 12, 2026 (P.C. 2026-610).
